Note: a new micro controller is considered to be compatible if it works instead of the old software and
the functionality is not significantly changed.
The following menu will be displayed whenever SDAM is entered. In this menu the error buffer can be

Geometry Adjustments
Notes:
1. The following Geometry adjustments were performed with a Sencore VG91 Universal Video Generator.
2. Set the VG91 Generator as follows: STD TV Ch. 3, RF-IF Range set to HI, RF-IF Level set to
NORMAL (1), Video Pattern = Raster, R-G-B raster controls OFF, crosshatch or center cross pattern
as required.
3. Connect the RF output of the generator to the Television Antenna Input, and adjust the VG91 level to
remove any snow from the raster.
Vertical Size (V-SIZE) adjustment:
1. Enter the Service Default Alignment Mode (SDAM) in either of the following two ways:
a. Press the following key sequence on the remote control transmitter while the set is in Standby
mode: 0-6-2-5-9-6-Status (Do not let the sequence time-out between entries)
b. Short service pin 0239 (on the CBA) to ground and switch power-on.
